I write things on the internet for fun. Sometimes fiction, sometimes scripting, something silly stuff. Also, I take photos, poke at random maker projects, and sometimes do my job @ Cocoa Press

Properly photographing a 3.5" floppy disk for archival is annoyingly complicated. The label has THREE sides!

I've already built an automated system to take a picture of the front of a disk, but really I need to take THREE photos if I want to get the whole thing.

That means either three cameras or I need to rotate the disk 90° and then 180°, which is going to really stress the limits of my mechanical engineering skills.

@foone May I share unsolicited printer advice? It looks in this photo as though the nozzle is partially clogged and is causing extrusion issues. You may get better results / less fragile prints if you get a needle or nozzle unclogger folks sell.

Annoyed to discover that Lychee Slicer's scene files are proprietary. I could spend the time to reverse engineer the format as long as it's not encrypted (it wouldn't be my first, eh @wamonite?), but I have much better things to do.

Does makes me want to stop paying for Lychee though and find another slicer. Only losers use secret formats.

Unfortunately it seems that most reisn printers are like that, the exceptions I've seen / looked at are Prusa's Resin printers, and the Prometheus MSLA project.

Is there an eInk / ePaper screen that's drivable via some sane mechanism that is wide? Like, there's those automotive displays for normal HDMI / VGA driven video that are 1280x360 or 1920x480 which are ideal, but I don't know if something exists in a single display for ePaper / eInk.

Any help / pointers appreciated

Is there a semi-modern way to stripe multiple discrete computers together in a semi-transparent way to present "contiguous hardware"? I wanna take a pile of trash computers and make htop show them as being "one device" purely for the joke.

OpenSSI was a thing but it seems dead. @nyanotech brought up a qemu patch at some point that might've done something similar? This is not practical I know but it'd be fun.

Maybe my knowledge is set in 2007 with ROCKS and openMOSIX stuff.

Green benchy from the Bambu Lab P1S, white benchy from the Prusa MINI+ w/5.1.0-alpha1 firmware... The green is definitely a better print.

I got the Prusa about two years ago because I wanted better quality prints that I was getting from my old printer. I care more about quality that speed...

I'll try a slower print and see if the new firmware has better quality.

(The P1S is fast and good quality.)

Two 3D printed benchy models.

@rasterweb @petrillic My understanding (obvious bias, work product is in main PrusaSlicer repo now) is that they spent a long-ass time trying to unify their firmware across their product lines, so the MINI firmware is very alpha, and this is to prove the concept / get more data.

The other thing I've found is that different filament colors can behave differently with I.S. since they have different additives. Might be worth doing an apples-to-apples test?

So I just did a print of a part for work and on the Bambu Lab P1S it took about 30 minutes... On an Ender-3 S1 it takes 1 hour and 30 minutes. That's at "normal" speed on both machines.

We do have 6 Enders at work, so in theory they can still kick out twice as many in the same time but still... that's quite a time difference!

(And buying one P1S would still be cheaper than buying three Enders.)

@rasterweb Faster printers are a gamechanger. At work we'd been using the MK4 with Input Shaper's alpha since the day it was released since it was such an improvement overall.

something is very, very wrong with kicad svg or pdf output (schematics). the file is only 500kb but manages to crash or crawl both scribus and inkscape. when exporting a pdf from scribus with the kicad file included, the file size balloons to 1.8GB

@mntmn

I was of the understanding eeschema produced PDFs through the system print driver, (File -> Print -> etc) Is it possible it's bug introduced in some other part of the non-KiCAD stack?

I'm on Windows though, so maybe not the most useful note I can't replicate it in nightly 😆

I made the mistake of browsing some Bambu Lab groups on Facebook. Lots of crazy people, and I just read dozens of comments about using glue sticks or hair spray for a normal PLA print… what!?

k1m,
@k1m@chaos.social avatar

@rasterweb It feels wild to me in the era of modern flex build plates to need it that badly tbh... Not just you

@lytta @rasterweb @Siff @chendo

Honestly I had issues with my MK3's satin bed because I had dust get on it, I washed it and it's fine again. After months of disuse, of using it for years overall.

Old habits can definitely stick (pun intended)

Exotic materials make sense, but PETG and PLA are... basically commodity at this point. Glue on glass is also a viable strat, so that makes sense.

I'd love to find a simple/cheap way to have one Arduino send data to multiple computers. (USB/USB MIDI though, not serial data.) I'm not even sure it's possible...

@k1m@chaos.social avatar

@rasterweb

Add a discrete Serial USB IC to the board on a serial port that isn't already used and it should work like you're hoping. That, or use TinyUSB to bitbang USB host on a non-USB serial pin.

@k1m@chaos.social avatar

@rasterweb The CH340 and the like should still work, but a second arduino is likely easiest / cheapest.

k1m,
@k1m@chaos.social avatar

@rasterweb You may end up just using the second microcontroller as a retransmission device; "on message from serial port here, emit to USB if connected, ok?"

If you want something more complex, it gets more complex. Should still be doable though?

@k1m@chaos.social avatar

@rasterweb You got this!
